The object of this invention is to provi-de an improved yconstruction for a Istove particularly adaptedfor Vuse in the boiling down of sirup 'and for similar purposes.

vide an eiicient and economical construction Jfor a stove of'l'arge capacity, and which is of especially rugged and durabley construction so that it may be continuously operated for a considerable period oftirne.` 'f I With these and other objects? invi'ew my invention consists l in the construction, arrangement and combination ofthe various parts'of my device, vwhereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated inthe accompanying drawings, in which:

Figure 1 is a plan View stove, partly in section. v

Figure 2 is a side elevation of the same, partly in section.

Figure 3 is a cross section on the line 3-3 of Figure 2.

Figure 4 is a cross section on the line 4-4 of Figure 2.

'5 A further object ofthe"V `nvention is to pro*- of my improved Figure 5 1s a detail sectional view, illustrating the method of providing a finished construction at the base of the stove.

ln the construction of my improved stove, I empl-ey a base plate 10 on which is mounted the housing. The housing is composed primarily of a top plate 11, side walls 12 and end Walls 13. TheA side walls and end walls are rformed at their lower margins with outturned flanges 14, which rest on marginal portions of the base plate 10 and are secured thereto by bolts or riv-ets 15.

Within the lowerpart of the housing is a supporting plate 16 having downturned Inarginal flanges 17 terminating in inturned flanges 18. The flanges .18 rest on the base plate 10 and are secured thereto by rivets or the like 19. n

Marginal portions ofthe base plate 10 are turned upwardly to form flanges 20 within which the base llanges 14 of the walls lit. The flanges 14, rivets 15 and upper edges of the flanges 2O are covered by finishing strips 50 I21 held in place by screws or the like 22.

.The end portions ofthe housing are .eX-

. tendedupwardly to form smoke bones23 and .24and'sai'd vsmoke boxes are provided .with suitable .'.flues2'5 and v26.respectively. f

Within the housing and preferably.eX-'x55v tending throughout ithe greater portion of fthe length [thereof is a lire box structure ,in-

cluding a'bo'ttom wall 27 lresting-oil the supporting plate16, and side walls 28 arranged i just .Within @beheersing Wang 12. Airb@ .we f

torn of the fire box structure an ash pit 29'. is formed, and centrally above this is a grate 30.' Extending upwardly from opposite sides of the grate are inclinedfire bei; walls,4 p

31 which are connected at their upper ends t with the side walls 281. The lireboir wallsl may .slope to any desir'eddegreeto 'suit par? ticular purposes,` such as fordiferent kinds offuel; f' g Access may be had 'to the upper portion o the housing through gany desired number of openings c losable by hinged fuel doors-32.' Access maybe hadv to the -lowerfportion of the housingfthrough anynumbel? Of'SU'mbly Y75 located openings .communicating with the ashpit 29 and closableby hinged ash doors'BB.

Those portions between the lire box wallsv 31; and sidewalls 28 constitute ovens 34 to which accessmaybe hadthi'ough door opens ings'closable by'hinged-doors 35. The ovens @so are here 'shown as KAprovided]with 4horizontal partitions'tl.H .Flu'e openings 37-are formed 'i through lower portions "of the'flre ybox walls 31',"normally closed'lby'fmeans of slidable 85 damper'valves 38.

A cover'p'late 39 isproyided. forthatI portion of the housing .between thefsrnolre loo-Ties YQiiand 24. The cover plate39 is of lessy width than the top wall 11 'of thefhousin'g and is 9G littedfwithina rabbet ordepres'sionformed in the upper ysurface of said top ,platel Thetop plate 11 ofthe housing isformedfk with a plurality .of openingsi40 andthe cover plate is .formedwith axplurality 'of y.larger,95 openings 41. The openings. 40 kmay be placed ingroups arranged beneath or with-'special relation tok theflarger openings v41 of thev members'BQ, as shown particularly in Fig.- ure l. y

filo

the fiues 25 and 26.

Juices or other substance to be boiled may be placed in suitable containers which are vmounted upon the co-ver plate 89 and a lire is built and maintained within the fire boX of the housing by means of fuel placed upon the grate 30.

The fire box communicates at its ends with the smoke boxes 23 and 24, as indicated in Figure 8, so that products of combustion may pass to the smoke boxes and Athen out through At opposite sides of each smoke boX 23 and 24 are placed reservoirs 42 and 43 adapted to contain water which is heated by vlire .in the stove. Each reservoir is provided with a removable cover 44. Access may be had to the reservoirs through openings in the top' of the housing at the sides of the smoke boxes. These openings are provided with removable covers 45.

Removable ash pans 46 may be placed in the pit 29 for convenience in receiving and removing ashes which fall through the openings of the grate 30.

It is to be understood that my improved stove may be made of any desired size and proportions and that various modifications and changes may be employed within the scope of the appended claims without departing from the real spirit of my invention.

I claim as my invention:

l.; A stoveof the characterdescribed, com- Y prising a housing,the top wall of said housing being formed with a rabbeted depression and also being formed with a plurality of relatively small openings therethrough, af

cover pla e mounted in said depression, said cover plate being formed with relatively large openings therethrough, each registering with a group ofthe smaller openings in the hous` ing topwall, and a grate in the lower part of said housing. Y

2. A stove of the character described, comprising a base plate, a housing havingwalls formed at their lower margins with outturned flanges resting on' and secured to marginal portions of said base plate, a supporting plate having downturned marginal flanges terminating in inturned flanges resting on vand secured to said base plate, and a fire box structure within said housing resting on said supporting plate.

3. A stove of the character described, comrisincr a base late a housing having walls formed at their lower margins with outturned flanges resting on and secured to marginal portions of said base plate, a supporting plate having downturned marginal flanges terminating in inturned flanges resting on and secured to saidbase plate, and a fire box struc- Y ture within said housing resting on said sup porting plate, said base plate being formed with peripheral upturned flanges within which the base flanges of the housing wall` snugly lit.

`porting plate, said base plate being formed *With peripheral upturned flanges within which the base lianges of the housing wall snugly fit, together with finishing strips mounted on and covering the base flanges of the housing walls and the upper edges of the upturned flanges of the baseplate.

5. A stove of the character described, comprising a'housing having a top wall, a cover plate mounted substantially parallel with said top wall, one of said parallel members being formed with a purality of openings therethrough, the other of said members being formed with groups of relatively smaller openings, each group being in substantial registry with one of the openingsof the first mentioned member, and a grate in the lower part of said housing.
